Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 3-Oxo-3,4-dihydro-2H-1,4-benzothiazine-6-carboxylic acid,272437-84-0, This compound has unique chemical properties. The synthetic route is as follows.,272437-84-0
Acid (4a) in tetrahydrofuran (SOmL) and triethylamine (4.7mL) was cooled to 0C and isobutylchloroformate (4.02mL) was added dropwise and the solution was stirred at 0C for 2 hours, when it was filtered into a stirred solution of sodium borohydride (3. 14g) in ice/water (50mL). The mixture was stirred at 0C for 1 hour and allowed to warm to room temperature. It was acidified with 2M hydrochloric acid, evaporated to half volume, and the resulting product was collected, washed with water and dried in vacuo, to give a white solid (4. 5g). MS (-ve ion electrospray) m/z 194 (M-H)-, 272437-84-0
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 272437-84-0.
